Re: [PATCH v1 1/1] mfd: intel-lpss: Switch over to MSI interrupts

Maybe it's much to ask, but I would really appreciate it if someone
looked into intel-lpss supporting these devices.
Been using a laptop without a functional touchpad over months now.
If that helps, there is another thread here
https://bugzilla.kernel.org/show_bug.cgi?id=218444 with perhaps more
details on the problem.
Battery and speaker are not a big deal, but the not working touchpad,
which I believe should be handled by an intel-lpss driver, is kind of
painful.
If you need any help from my side, testing patches, don't hesitate to
contact me.

Regards,
Mateusz
